10 Claims.

My invention relates to metal store front construction and particularly to a metal sash for the large plate glass panes used in store fronts. An object is to provide an improved metal sash assembly for large plate glass panes, such as are used in stores, and a purpose of my invention is the provision of an improved metal sash of this character which is simple, sturdy, inexpensive, and adaptable to artistic forms and which comprises a minimum number of simple, easily manufactured parts that are capable of being readily assembled in position to support the glass pane. My construction is of that class wherein the fastening devices that secure the sash elements in place are inserted from the rear and are not exposed to view from the front. Fastening elements which are in large part concealed have heretofore been employed in this industry, but an advantage v of my invention is that the arrangement and construction is such that these fastening devices can be quicklyinstalled and are positive in their functioning.

My invention has as an object the provision of a construction consisting of few simple parts wherein the holding parts may be made strong to take the strain and the more decorative parts may be made of metal relatively less strong. The parts which constitute my invention are easily transportable in suitable packages without injury. They adapt themselves readily to interfitting assembly. They are of such a character as to be capable of manufacture in a variety of artistic shapes without loss of their advantageous mechanical functioning.

A meritorious features of my invention is that there is associated with the face plate portion of the sash a series of detachable elements which are carried thereby but adjustable lengthwise therealong and which extend underneath the edge of the glass pane and engage the set plate or gutter portion of the sash and are connected therewith by suitable fastening devices to hold the two parts of the sash against the opposite faces of the glass.

The above objects and others will more fully appear from the following specifications, appended claims, and accompanying drawing wherein:

Fig. l is a perspective of the face plate portion of my metal sash,

Fig. 2 is a perspective of the set plate portion of the sash,

Fig. 3 is a section through one of the supports for the glass pane, and

Fig. 4 is a horizontal sectional view through the assembled sash shown in its supporting relationship t0 the glass pane.

In the drawing the face plate is indicated generally by the niuneral 10. It has a channel shaped bottom portion 12, the lower wall 14 of which is adapted to rest upon a stationary part such as a sill 16. The face plate has along its upper margin a channel indicated generally as 18 which has an inner deflected wall 20 a portion of which bears against the glass pane 22. The glass pane is self supported upon elements 24. These are shown in each of the figures of the drawing. They comprise generally channel shaped metal members which rest upon the sill and which carry a cushioning seat 26 of lead or other suitable mate- 7o rial along the upper surface against which the edge of the glass rests.

The set plate or gutter member is indicated generally at 28. It has a base 30 which has an upturned edge 32 that is received within the channel 12 of the face plate and overlies the side wall 14 of the channel 12. This gutter member is formed in such a fashion as to have a channel portion 34 along its upper edge which has an outer sidewall 36 that rests against one face of the glass pane. The glass pane is therefore positioned by the wall 36 and the channel 34 and the wall 20 of the channel 18 of the set plate and face plate respectively. The channel34, due to its formation, provides a groove within the interior of the set plate. This groove is formed between one side wall of the channel and the opposite wall of the set plate.

The bottom of the channel 34. is provided with apertures 38 through which securing means are inserted in a manner hereinafter described to hold the set plate and face plate against the opposite sides of the glass pane.

I provide a plurality of channel shaped elements indicated generally as 40. Each of these elements has a slot 42. This slot is of such a width as to register substantially with the aperture 38 in the channel of the set plate. These channel elements 40 are secured as shown in Figs. 1 and 2 to the face plate. Each channel 1 0 element 40 has a side wall which is inserted within the channel 18 of the face plate. Due to the deflection of the wall 20 of this channel 18 and the fact that the construction is of sheet metal possessing inherent resilience and that the aperture of the channel is of such a size as to permit the insertion in the side wall of the channel member 49 therein to be frictionally gripped thereby, the channel member 40 is held by the frictional gripping engagement of the side wall 20 of the ments l firmly up against the set plate and also decorative character which is relatively light in channel 18 against the side wall of the channel member 40 which is inserted within the channel 18. This is shown in Fig. 1.

The channel elements 40 are arranged in spaced apart relationship lengthwise of the face plate and may be shifted lengthwise to bring them to desired positions therealong. When the device is installed to support a glass pane the set plate 28 is first positioned on the sill and secured by means of screws 44. The glass pane 22 is placed upon the blocks 24. which are arranged at suitable places along the sill. The channel elements 40 are then inserted within the channel 18 of the face plate as shown in Figs. 1 and 2 to be carried thereby and are arranged at the proper intervals and the face plate is then brought into position with the channel elements 40 extending underneath the edge of the glass pane between the supports 24, as shown in Figs. 1 and 2. These channel elements 40 engage in the manner shown in Fig. 4 so that one side wall engages within the groove in the set plate 28. Screws 46 are then inserted through the apertures 38 and threaded into the slots 42 in the channel elements 40. Due to the use of slots in the elements 40 it is readily possible to insert and fasten screws without feeling for the aperture, as would be the case if round apertures similar to 38 were provided in the elements 40. Tightening of the screws 46 draws the channel eledraws the face plate channel portion 18 firmly against the face of the glass pane so as to snugly grip the pane between the face plate portion and the set plate flange 36.

Due to providing the channel portions as a separate element as compared with cope nding application Ser. No. 487,837 of this applicant where these channel portions are integral with the face plate, it is possible to arrange such channel portions relatively along the length of the face plate and it is further possible to provide such channel portions in different metal than that of the face plate. It is frequently desired that the metal of the face plate be of a weight and the channel elements 40 take the strain of the screws 46.

A further advantage in having these separate is that it is an easy job of manufacture as the parts are more simple in form and, further, the parts may be assembled for shipment in a more convenient package than if the channel elements 40 form an integral part of the face plate 10. The metal sash structure here shown is adaptable to be made in various forms or shapes which conform to a predetermined type of architecture. It may be of modernistic or other design. The functional purposes are served equally regardless of the shape.

I have illustrated a preferred embodiment of my invention in the accompanying drawing but I intend to limit myself only as within the scope of the appended claims, as other embodiments are equally available.
